Course Documents -> Week 2 -> Another Google Earth Exercise
This time we will try to discern transmission line infrastructure:

download the worksheet

    1. Let's begin in Eugene and find the Ridgeline trail and try to follow the treeless corridor for as far as you can. Identify, in the worksheet what you think are the beginning and ending coordinates of the power corridor and what the overall length is.

    2. The Indiana-Ohio voltage line

      • go to coordinates 41 53 10 -86 11 21 and notice a big white electricity distribution center. Follow the transmission corridor that goes to the NorthWest (and eventually it will start going mostly West). Keep following it (notice when it crosses a river) as far as you can until you eventually get to where it Merges with a set of lines that go North South. Enter in the Coordinates of that location, and determine the overall distance from that point back to the starting point.

    3. Grand Coulee Dam
      • Find the Dam - find the big distribution station a bit southwest of the dam. (There are lots and lots of wires). Now try to follow one of the main lines that goes southwest and follow that to the first distribution station that you find. Enter in the coordinates of that distribution station and the distance from it to Grand Coulee Dam station.
